One thing you can do is hook up a serial cable to the Receiver and see if it's attempting to do anything at all.

You need to build a level converter board to do this. See Jeff Mock's page at http://www.mock.com/receiver/server/, for example (scroll down to the section titled "Console").

This will allow you to see if the flash has failed, or if it's something else, like the screen driver.
